Regardless of whether they codify existing implementations or innovate
far beyond them, programming language standards are codifications - and
that makes them prescriptive documents. The C++ standard exists to
define what it means to be a conforming implementation of C++, and what
it means to write well-formed code. Well-formed code translated by a
conforming implementation of C++ will produce the behavior that meets
the requirements specified by the standard - and that's the point of the
standard.

However, C++98 was in fact notorious for the extent to which it went
beyond merely codifying existing practice. In particular, <iostream> was
a big change from <iostream.h>, and the process of incorporating STL
into the C++ standard library involved a lot of changes.
And every revision to the C++ standard has increased C++'s reputation
for innovating well beyond existing practice. The language defined by
the latest standard is very different from the one defined by C++98.

The other standard that I'm most familiar with, the C standard, is by
comparison a very slowly changing standard - but C90, C99, and C2011
were all pretty significant changes from existing practice.
